A)
Obw = 10 + 10 + 10[tex]\sqrt{2}[/tex] = 20 + 10[tex]\sqrt{2}[/tex] = 10*(2+[tex]\sqrt{2}[/tex])
P= 10* 10 * [tex]\frac{1}{2}[/tex] = 50
B)
a [tex]\sqrt{2}[/tex] =12 więc a = 6[tex]\sqrt{2}[/tex]
Obw = 6[tex]\sqrt{2}[/tex] + 6[tex]\sqrt{2}[/tex] + 12 = 12 + 12[tex]\sqrt{2}[/tex] = 12*(1+[tex]\sqrt{2}[/tex])
P= 6[tex]\sqrt{2}[/tex] * 6[tex]\sqrt{2}[/tex] * [tex]\frac{1}{2}[/tex] = 36
C)
a [tex]\sqrt{2}[/tex] =14 więc a = 7[tex]\sqrt{2}[/tex]
Obw = 7[tex]\sqrt{2}[/tex] + 7[tex]\sqrt{2}[/tex] + 14 = 14 + 14[tex]\sqrt{2}[/tex] = 14*(1+[tex]\sqrt{2}[/tex])
P= 7[tex]\sqrt{2}[/tex] * 7[tex]\sqrt{2}[/tex] * [tex]\frac{1}{2}[/tex] = 49
